 103 This module is intended as a shim to ease the eventual transition from
 104 having all barcode-related code in the value builder plugin .pl file
 105 to using C4::Barcodes. Since the shift will require a rather significant
 106 amount of refactoring, this module will return value builder-formatted
 107 results, at first by merely running the code that was formerly in the
 108 barcodes.pl value builder, but later by using C4::Barcodes.
